Created by Hollywood vocal coach Seth Riggs, Speech Level Singing (SLS) is a revolutionary vocal training technique that maximizes your vocal abilities in any style of singing.

From Opera to Rock; Jazz to Pop or R&B, over 120 Grammy award winners use it. SLS has also been practiced by Academy Award winning actors and industry leaders to perfect their vocal presence and empower them in speech.

In many cases SLS rehabilitates vocal damage caused by poor teaching or years of abuse, that could otherwise limit or even end a career, or worse - require continual medical intervention. SLS training will both improve your voice allowing you to sing safely and with greater range, no "cracks," "breaks," or losing strength in the middle connection.

Speech Level Singing is a way of using your voice that allows you to sing freely and clearly with maximum power and clarity.

Since you are not learning what to sing but rather how to sing and maintain an even balance through your bridges, you can apply this technique to any type of music.
